Is it bad to turn the engine on and off frequently

[danegoesonline]

Im a Grab Driver and after I drop the passenger off I am turning off the engine to save fuel consumption, after 5-10 minutes I will start it again. Is this ok? Am I shortening any parts of my car? Please help, I will appreciate it very much.

No problem and you also help save our environment [emoji106]

ok lang yan. some newer cars even have auto start stop systems. automatically kills engine when idling

starter is an electric motor and is usually very reliable

what's bad are repeated short trips. like starting cold then driving 1km. then rest 1hr. starting cold again. rinse repeat

Pero ano po yung na wear na parts pag nag iistart ng engine? Spark plug?

IMO sir battery madali masira sa ganyan senaryo lalo na maiksi lang takbo kung sakali:-)

1. Battery
2. Starter motor carbon brush, solenoid contacts and starter pinion gear. Yung carbon brush madali lang palitan. Most starter solenoids are now sealed type so palit yan buo. Also the pinion pag nabungi or worn out palit na agad at baka kasi madamay ang flywheel gear.

Another question related to battery. Coding ako yesterday so kinailangan ko magstay sa office ng matagal. I accidentally left the parklight on po for about 16hrs. My battery was not drained pero may chance po bang sandali ko na lang magagamit yung battery? Hyundai Accent 2016 model po.
Thank you!

i keep all my battery receipts so i could track battery lifetime

there was one time i had to go abroad for 2 months so i just left the car and no one started it for 2 months. needless to say it got overdischarged

guess what, that particular battery lived just as long as the others. so apparently there's another failure mode that kills the battery faster than sulfation from overdischarging would

kung short trips, battery siguro ang pwede maapektuhan. easily remedied by buying a smart charger

i used to that with my diesel, during long stoplights.
hayun... battery died on the 13th month, 1 month after warranty expired.

Doc, in my experience with Motolite Gold , patama talaga ang life nya sa warranty na 21 months, minsan lang ako naka tyempo ng more than 2 years and malas na na trade in ko pa for a new one due to mis diagnosis of faulty alarm module.

Paps alam mo ba pagkabasa na pagkabasa ko ng reply mo ayaw na magstart ng tsikot ko, mag pajumpstart pako sa motolite.

A sensible question to ask. It all comes down to the health of the entire electeical system. Grab driver, your car must be newish right? System should be fine to turn on and off.
The situations where it would be a problem...
An aged battery, would take a significant boost charge to recover after every start compared to a newer battery. So if you constantly did this stopping and starting on an older tired batery, 2 bad things would start occurring.
1. The current going through the starter motor would start increasing and starter motor life would be shortened due to the resulting heat, and
2. The current needed by the alternator to replenish the significant discharge that the older battery took when supplying said current to the starter, would start increasing, shortening the life of the alternator.

So put simply, stopping the engine is really economical, only if your batterys health is at least 70%. If the health is lower than that (as measured on a decent industrial workshop battery tester) then you may actually be expediting the death of multiple electrical components beyond the value of the fuel saved.

One more factor, is fuel type. Diesel engines are significantly more efficient at idle than gasoline. So the battery health threshold for where this economical cutoff would be for a gasoline vehicle is slightly lower than an a diesel. i.e, a gasoline engine might be better off switched off rather than idling at 70% battery health, but a diesel uses ao little fuel at idle it might better left on, unless battery health was so good it did no harm to the battery health.
I hope that makes sense.

If I may ask, aside from using hygrometer, is it possible to know the health of your battery by using a multimeter?

Search "battery tester" in olx or lazada.

encounter ko ito sa motollite wala pang 1 year nasira kaagad buti under warranty pa kaya palit ng bago...kaya mas maganda kung mga 5 mins lang naman hintayin mabuti pang wag patayin nalang makina.kasi battery at starter ang maaring masira.

As long as your trips are about 5 kms or 15 minutes, your vehicle will be fine ... Prolonged idling also has more drawbacks compared to frequent starting and stopping of engine ... As long as they are not very short trips (1-3 km or 5 minutes) ...

Naku e puro short trips ako e.

I find it hard to accept that starter motors have gotten so fragile?

The only way I could imagine trashing one of these was by continuously cranking the engine (i.e. pinipilit i-redondo) that won't start because of some other mechanical problem. You can cause the starter to overheat.

Switching the engine off and starting it again, even frequently (yung within reason of course, not yung 100x in 5 minutes!) shouldn't be cause for much concern. Ewan ko lang ngayon though. Generally, they should last the designed service life of the vehicle.

As to batteries, cheap brands do last a year only. Getting 3+ or more years on one of the better models, tingin ko sulit na.

when our wigo AT's original battery died, we could not jumpstart her!
we consider ourselves experts on jump-starts and push starts, with years of experience, courtesy of our pesoless beginnings when we were still students. but we could not jumpstart that wigo.
we finally surrendered and called battery delivery. upon replacing the battery, the car started like nothing happened.
